It routes one of two analog or digital signals to a common output, controlled by a logic-level select pin. The part is built for precision applications that need low on-resistance (35 ohm max), fast switching (175 ns turn-on, 145 ns turn-off), and good channel isolation (-85 dB crosstalk at 1 MHz). It operates from a single supply of 10 V to 30 V or dual supplies of ±4.5 V to ±20 V, and is rated over the commercial temperature range of 0°C to 70°C. Typical uses include audio signal routing, data acquisition front ends, and test equipment multiplexing. ## Supply voltage and temperature — fit check The single-supply range of 10 V to 30 V covers common industrial and instrumentation rails. The dual-supply option (±4.5 V to ±20 V) lets the switch handle bipolar signals without level shifting. The 0°C to 70°C temperature grade means this part is intended for indoor, controlled-environment equipment — office peripherals, benchtop instruments, and consumer audio — not for automotive or outdoor industrial use where extended temperature is required. ## Lifecycle and sourcing The MAX319CSA+T carries an active lifecycle status, so there is no imminent end-of-life risk. It is ROHS3 compliant. No official second source or direct replacement is listed in the record, so dual-sourcing would require qualification of a functionally equivalent SPDT switch from another vendor.","metaTitle":"MAX319CSA+T Analog Devices SPDT Analog Switch, 35 Ohm","metaDescription":"MAX319CSA+T SPDT analog switch from Analog Devices. 35 ohm on-resistance, 175 ns switching, -85 dB crosstalk at 1 MHz.
